The value of the resistance at the full filling (\(\nu =\pm 4\) ) continuously decreases with increasing temperature up to much higher T \(\sim 100K\) . On the other hand, the value of the resistance at \(\nu =0\)  and 2 decreases with increasing temperature up to \(\sim 10 K\)  and then increases linearly, showing metallic nature (SI-10). These observations are consistent with earlier reports for MtBLG [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}. The gap (\(\Delta \) ) determined from the activated plot for \(\nu =0\) , \(\nu =2\)  and \(\pm 4\)  are, respectively, \(\sim \)  \(0.05meV\) , \(0.25meV\) , \(11.5 meV\)  and \(9.25meV\)  as shown in the SI-10 and SI-11. Furthermore, it can be seen (SI-10) that there is a crossover from metallic nature to insulating one at a higher temperature due to interband excitation of the carriers between the flat and dispersive bands. From the crossover temperature, \(\sim 150K\)  around the Dirac point, one can estimate the bandwidth (\(2W\) ) and found to be of the order of \(\sim 10 meV\)  for the MtBLG. In Fig. 1e and 1f, we have shown the differential resistance versus bias current with temperature and perpendicular magnetic field around the superconducting dome. In order to extract the transition temperature at a giving filling, we compare the experimental data with the theoretically generated critical current versus temperature using BCS theory, \(I_{c}(T) = I_{c}(0)(1-T/T_{c})^{2}\) , where the \(I_{c}(0)\)  is the experimentally measured critical current at \(T = 20mK\) , and vary the \(T_c\)  such that the theoretically generated \(I_{c}(T)\)  traces the experimentally measured \(I_{c}\)  in Fig. 1e. This was repeated for other carrier densities and shown in the SI-12. The extracted the critical temperature was found to be \(\sim 500mK\)  at \(\nu \sim -2.5\)  (SI-12). The measured value of \(T_c\)  and critical field (\(B_{c} \sim 100mT\) ) of our device matches reasonably well with the available data for MtBLG [6]}, [2]}, [5]}, [7]}, [4]}, [8]}.
Note that the Fraunhofer-like pattern in Fig. 1f can be explained by the interference between percolating superconducting paths separated by the normal islands, which is generic feature in MtBLG due to twist-angle in-homogeneity [15]}, [16]}, [8]}. These patterns further establish the existence of the superconductivity in our device though the measurement was carried out in two-probe geometry.
